GNX3 MIDI/USB connection to computer

I know it's a little dated, but I have a Digitech GNX3. I want to connect to my computer to save patches with a MIDI to USB device. The GenEdit software keeps giving it can't find digitech device. The cable is cheap (ebay for like a buck) and may be part of the problem (sorry I have kids, a mortgage and other responsiblities). Does any body have any ideas? Is there additional software needed (for the cable)?

I tied switching the in and out. Several other threads said to make sure the out from the computer went to the in on the GNX3. I did not look for a MIDI driver. When the cable was first plugged in, it loaded some kind of driver. The other threads said the driver may be the problem.
